SpaceX successfully re-launches its first used rocket

Elon Musk-led space exploration startup SpaceX has successfully launched its pre-used first stage of Falcon 9 rocket in its bid to drive down costs and speed up flights. It marks the first time relaunch of an orbital class rocket. The Falcon 9 took off from Florida’s Kennedy Space Center hoisting a broadcasting satellite. The reused first stage was earlier used in March 2016 and had successfully landed on drone platform.
